Find the length and width of the base, then multiple those numbers together to determine the area of the base. Next, multiply the area of the base by the height of the pyramid. Then divide the result by 3.
Answer: D
The two aquariums are not similar, and the volume of the new aquarium is 4,320 cubic inches.
Step-by-step explanation:
If the two aquarium are similar, then, there should be a scale factor for their similarity. Since their is no scale factor fit for their similarity, we conclude that they are not similar.
Also, the volume of the old aquarium is 5,184 cubic inches. This shows that non of it parameters ( length, width and height ) is neither in multiple of 5 nor multiple of 10. It is therefore not possible for the new aquarium to be 3000 cubic inches since the new aquarium is with a length, width, and height that are each times as long as the corresponding dimension of his old aquarium. Base on these fact above, we can then conclude that
The two aquariums are not similar, and the volume of the new aquarium is 4,320 cubic inches.
Answer:
a)x+69+73=180°{sum of angle of triangle}
b)
let, another a unknown side be 'p'
p=65°{alternate angle}
65+65+z=180°{sum of angle of triangle.}let ule
130+z=180
z=180-130
z=50°
- y+z+65°=180°{straight angle}
- y+115=180°
- y=180-115
- y=65°
z=x{alternate angle.}
x=50°
so, x=50°, y=65°, z=50°
c)z+19°=180°{straight angle}
z=180-19
z=161°
- z=y{co_interior angle}
- y=161°
d) 67+35+x=180°
x=180-102
x=78°
- y+67=180°{straight angle}
- y=180-67
- y=113°
- 35+z=180°{straight angle}
- z=180-35
- z=145°
2)
3x+10+2x-5+x-5=180°{sum of angle of triangle}
6x=180°
x=180/6
x=30°
hope it helps.
16x+2(3x-5)=-32
16x+6x-10=-32
22x-10=-32
22x=-22
x=-1
